The housing crunch in Jackson, Wyo., is expected to get even tighter this summer. Bridger-Teton National Forest officials announced in April that camping on forest land in the Jackson district this summer will be limited to five days, cut from 16. This worries the Jackson Hole chamber of commerce, since 1,200 seasonal workers usually move into the forest during warm weather. Chamber director Joe Rogers says affordable housing is already tight because three private campgrounds recently closed after the land was slated for development. While Teton County Commissioner Sandy Shuptrine said she supports cracking down on squatters, some of whom cause law enforcement problems, she'd like Forest Service officials to develop a new campground just for seasonal workers.
